  • [gentoo-dev] How to add -std=c++14 to CXXFLAGS of a cmake.eclass based

    From Andrey Grozin@21:1/5 to All on Sat Dec 17 12:40:02 2022
    Hello *,

    I'm trying to package a new version of sci-visualization/gle which now
    uses cmake. After some patching CMakeLists.txt, it configures
    successfully. But at build time it spits zillion errors

    error: ISO C++17 does not allow dynamic exception specifications

    The natural thing to try is to add -std=c++14 to CXXFLAGS. So I tried

    src_compile() {
    CXXFLAGS="${CXXFLAGS} -std=c++14" cmake_src_compile
    }

    but this makes no difference, c++17 is still used. How to convince cmake_src_compile to use -std=c++14?

    Thanks in advance,
    Andrey
